say，tell，speak有什么区别
"Say," "tell," and "speak" are all verbs that involve the act of communicating or expressing oneself. However, they have slightly different meanings and usage. 1. "Say": This verb is quite general and can be used to refer to any act of expressing oneself verbally. It is often used to report someone's words or to convey information. For example: - He said he would be here at 5 pm. - She didn't say anything about the party. - Can you say that again, please? 2. "Tell": This verb implies a speaker conveying information or giving instructions to someone specific. It usually involves a direct object - the person to whom the information is being conveyed. It is often used when sharing a piece of information or giving commands. For example: - He told me about his plans. - Please tell her to meet me at the café. - Can you tell me where the nearest gas station is? 3. "Speak": This verb refers to the act of verbal communication in general. It can be used in various contexts, such as discussing languages, talking in public, or simply engaging in conversation. Unlike "tell," it does not require a direct object. For example: - He can speak three languages fluently. - She gave a speech and spoke passionately about her cause. - Let's speak about our plans for the weekend. In summary, "say" is a general verb for expressing oneself verbally, "tell" involves conveying specific information to someone, and "speak" refers to the act of verbal communication in general.
